| Popis: | Previous studies showed that animals dynamically change their survival strategies according to the surrounding environment. Animal studies suggested that the hypothalamus mediates this process. Arguably, the neural and behavioral mechanism of switching between different survival strategies in human has not been investigated. The purpose of this study is to investigate neural mechanism of switching between two different survival strategies, escaping from the predator and attacking the prey, in human. To investigate this question, subjects are asked to alternate between escape task or attack task such that the type of the task changes randomly. In the escape task, participants have to escape from the virtual predator. In the attack task, participants have to chase and catch the virtual prey. If participants fail in attack or escape task, they will occasionally get an electric shock with a 14% probability. After finishing one trial of the task, the type of task they play in the next trial randomly changes to another type of the task (switch condition, e.g., escape task to attack task) or stay within same type of the task (stay condition). After the participants are caught by the predator or catch the prey in some trial, the next trial starts with the ‘pre-encounter stage’. In this stage, there are no predator or prey and subjects can prepare for upcoming predator or prey. Participants will be asked about the confidence of each task for every 10 trials on average. Additionally, there is a control condition is also included to control for motor and attentional switches. This condition involves switching or staying between a task of collecting number from 1 to 4 in an ascending order or collecting number from 4 to 1 om a descending order. After finishing the experiment, subjects will perform a post-experimental survey. |
